The feature had debuted as a beta version in early June, and let users add images to tweets.

Clicking on the the new camera icon right below the “What’s Happening?” box will let you select a picture to upload from your hard drive - just like Facebook. You can also preview the photo before tweeting it to everyone.

Tweets with picture have their own link at pic.twitter.com, and the service is powered by Photobucket, an image hosting site. The size limit for these photos is capped at 3MB, and may affect the number of characters in the tweet.

These images can be seen in a Twitter search, unless a user has a protected account - in which case only followers can see the photo-tweets. This feature is only available for Twitter's desktop version, and has been made public before the launch of Apple iOS 5, which features better Twitter integration .

Another feature Twitter has added to it's interface is a better organized way of accessing important tweets - specifically related to tweets about you, as well as topics important to users in your network.

This will mean more visibility to tweets mentioning you (the @Mentions stream - now named the @Username tab) , and will also include a new tab called "Activity."

This tab lets you see the topics your Twitter-folks are talking about, and their favorite and retweeted tweets and any new follower they are adding. (MensXP.com)
